Macroscopic Description of an Ideal Gas

A rigid tank contains 0.40 mol of oxygen (02). Determine the mass (in kg) of oxygen that must be withdrawn from the tank to lower the pressure of the gas from 40 atm to 25 atm. Assume that the volume of the tank and the temperature of the oxygen are constant during this operation. This is how I solved it. I just want to co ...continues

Molar heat capacity at constant volume and pressure

When 117 J of energy is supplied as heat to 2.00 moles of an ideal gas at constant pressure, the temperature rises by 2.00 K. calculate the molar heat capacity at constant pressure and the molar heat capacity at constant volume for the gas. is the gas monatomic or diatomic?

Adiabatic condition and equation of state of an ideal gas

A sample of 8.02 x 10^-1 moles of nitrogen gas (gamma=1.40) occupies a volume of 2.00 x 10^-2 m^3 at a pressure of 1.00 x 10^5 Pa and temperature 300K. the sample is adiabatically compressed to half its original volume, nitrogen behaves as an ideal gas under these conditions. Show from the adiabatic condition and the equation of ...continues

Laws of Thermodynamics

Question: When a gas follows path 123 on the PV diagram in the attached file, 418 J of energy flows into the system by heat, and -167 J of work is done on the gas. a) What is the change in the internal energy of the system? I believe that I have this part correct. Change in U = Q + W = 418 J ...continues
